Thank you for the feedback! Yeah there's nothing further to do once you beat the rat king, I haven't finished any content deeper than that since it's still early days. I'll see what I can do about the controls and making them a bit more intiutive. Adding space as a command key is easy for sure.
As for the adult tag, I mostly just added that because most of my other games are furry smut and I still haven't quite decided if I want to go that direction with this one. I'm torn honestly. Right before I posted it, the stuff with Dirk was much more adult and I cut it all out at the last minute.
